The Waterberg-plateau Park is located 20 15' to 20 25' S. lat. and 17 5' to 17 28' E. long. The park is approximately 64 kilometres east of the town of Otjiwarongo. The vegetation can be descriptionbed as a homogenous deciduous tree savanna where the shrublayer has become closed thicket of mainly Acacia ataxacantha and Ochna pulchra. The vegetation of the Waterberg-plateau Park was classified into six major communities which were divided into a further 23 smaller units

The Chestnut Weaver Ploceus rubiginosus is a poorIy known species, which migrates southward to breed as far south as Windhoek. To date, however, its breeding cycle has not been studied in detail. Its apearance and disapperance are erratic, but may be linked to the equally unpredictable rainfall of this region.

A sequcnce of calcareous mudstones and sands is exposed in an interdune corridor of the Namib Sand Sea at Narabeb, 30 km south of Gobabeb. This 36 m section is unique in the region and is descriptionbed in detail.

The orientation behaviour of Pachyphaleria capensis (Laporte), a psammo-halophilic tenebrionid beetle of southwestern Africa, was investigated. Skototaxis and pilotage are the main mechanisms adopted by the beetle to escape solar radiation.

Population densities of Onymacris bicolor (Haag) (Coleoptera; Tenebrionidae), a locally abundant, endemic species of the Namib Desert, were estimated in four habitat types of the dunefields of the Skeleton Coast Park using the Lincoln Petersen Index and the Jolly Seber method

Precopulatory and copulatory sequences of mating behaviour are descriptionbed in a micrwhiropteran bat. After a brief period of courtship, copulation occurs in flight with both bats hovering. Copulation is of short duration and is repeated up to three times.
